Neither of the two CHP officers were injured.
The incident occurred at 2 a.m. on the eastbound 10, just east of PeckRoad, said CHP Officer Tony Polizzi.
The unit was parked on the right shoulder and the officers were outside dealing with another incident, said CHP Officer Francisco Villalobos said.
"A minivan and a dark sedan were involved in a traffic collision, and the minivan struck the patrol car and overturned,'' Villalobos said. The minivan driver suffered moderate injuries and was extricated by Los Angeles County firefighters and transported to a hospital for treatment.
The dark sedan, a Mitsubishi Eclipse, kept going, Polizzi said.
The patrol car caught fire and firefighters put it out, Villalobos said.
